This patch series adds documentation, 'DBG' statements, and balances
WISPr/portal context reference counting with proxy handling that leads
to a heap-use-after-free fault.

Grant Erickson (4):
  wispr: Add DBG statement to 'free_connman_wispr_portal_context'.
  wispr: Document 'wispr_portal_hash'.
  wispr: Add documentation about reference counting.
  wispr: Address unbalanced reference counting with proxy handling.
